[PyGame] Help! Character won't move!

[keyfive]

Hi, I am a new programmer. My red cube is not moving

import pygame
import time
import random
import sys

pygame.init()

#screen variables
sWidth = 1000
sHeight = 700

#colours
red = (255,0,0)
black = (0,0,0)
white = (255,255,255)

#Main mechanics
gDisplay = pygame.display.set_mode((sWidth,sHeight))
clock = pygame.time.Clock()
pygame.display.set_caption('Zube')

def gameStart():

    #Mechanics
    gDisplay.fill(white)
    pygame.display.update()
    clock.tick(60)

    #Shapes and stuff
    playerStartingx = 64
    playerStartingy = sHeight - 100
    player = pygame.draw.rect(gDisplay, red, (playerStartingx,playerStartingy, 60, 60), 0)
    LRC = 0
    pygame.display.update()

    #Game Loop Variable
    playing = True

    while playing:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()

            if event.type == pygame.KEYDOWN:
                if event.key == pygame.K_LEFT:
                    LRC = -50

                elif event.key == pygame.K_RIGHT:
                    LRC = 50

            if event.type == pygame.KEYUP:
                if event.key == pygame.K_LEFT or event.key == pygame.K_RIGHT:
                    LRC = 0


        playerStartingx += LRC

gameStart()
